the AW7x transmissions *ARE* Toyota Supra (and truck) transmissions. the AW71 Volvo used on the turbo 740/940 cars is a beefy version, and I've been told will do just fine up to 250HP, as will the Dana 30 based rear axle/differential.

if you want the ultimate in sleepers, see this thread

Yes, you can T into the radiator hoses.


There are plenty of crazy Volvos out there. Search for them. turbobricks is a start.

 

The thing i read said the supra trans can handle up to 400. Not sure how truthful but i do know the 2jz supra engine cranks some power so i could see it being true and alot of the 4x4 guys are putting small blocks into their rigs and keeping the toyota trans. I almost did till i found a good deal on the 3.0 that it came with. I also saw or read about a dohc 2.7l that seems to be a go to engine if you want a real mean volvo.

I stumbled on that thread once its cool but it lost me at 302. My brother and i are currently working on putting a healthy 327 into his 86 2wd toyota. I almost had to promise my grandpa that i wouldnt small block the volvo lol.

 

I got a membership on there i just havent had time to browse the forum yet. Im thinking a good 250-300hp would be real good for this old girl.

 

te key is, make sure your engine *and* car are totally in top shape BEFORE you start cranking it up. everything that can break, will break if you take it too far.

 

Oh yeah i know all about that. The last 2 times i went out 4 wheelin i "found" a weak part lol. I know about building cars this is just my first volvo build so i dont know what engines are the good ones what will work with what all that kind of stuff. Im too worried about the rearend it should take some abuse its the same basic thing that jeeps have. It will eventually get converted to a ford 9" or something like that anyways Its just the engine and tranny combo that i need to get figured out.

 

Hey pierce would you be able to tell me the size and thread of that banjo bolt. I am going to go and try to find one in a junkyard but if not im going to buy a couple new ones.

 

best I could do would be to look up the volvo PN's on it, otherwise, no idea. I'm not taking my mitsubishi turbo apart and anyways, they might not be the same.

hollow screw - qty 2 - 974678
gasket qty 4 - 11996
inner/lower coolant pipe qty 1 - 1378551
outer/upper coolant pipe qty 1 - 1378621

 

Cool thanks thats a start atleast. if i cant find anything im going to "redneck" it so it will work for a few months till i can get my engine swap ready. Do you know what that dohc 2.7L engine came in?

 

um, what 2.7L DOHC engine??

 

When i was doing some searching i saw a video of a guy building his wagon and he put a volvo dohc 2.7L engine in it or atleast that is what it looked like. Im almost 100% positive it was a dohc 2.7L volvo engine.


Thats the video. I just skimmed it again and all he said was crate motor from sweden. This was a serious build though

 

says its a b230f k-block, which *was* 2.3L before they stroked and bored it. looks like they used the DOHC head from a B234F, whihc was used in a few 16 valve 740/940's.

good god, that sound track was obnooxious

 

LOL i never heard the sound track i had my speakers off on my computer at work. So It was basically the engine you told me to use but just on steroids. Looks like a very pricey build. Were the B234F engine just not used very much in the U.S.? Just wondering so i can cross my fingers when i go to the junkyard. What is the difference in the K-block from a B230FT?

 

actually, huh, I googled it, the B230FK is a european-market-only low pressure turbo version. obviously they just used the block, as that didn't come with the twin cam.

the B234F 16 valve sold here were nice engines, they revved higher, and came with a AW72 gearbox that had lower gears so it would run higher in the rev band. the dual cam had a counterbalance shaft system that made them smooth. They have as much HP and nearly as much torque as the turbo albeit at much higher RPMs. They are interference engines (break the timing belt and bend valves).

 

I hate interference engines. So the combo would be a b230ft block. The head from that other engine and either of the trans should be fine. I would need the computer and harness from the b234f i would think

 

I would start with the LH 2.4 system thats attached to the 93-95 B230FT. basically transplant the whole harness from the 940

actually, I would leave the B230FT LH2.4 system *in* the 940 and use that as my platform, hahahahah, fixing it up. they are quieter and have nicer interiors and come with better brakes.

 

Of course it has a nicer interior lol its 15 years younger. My 244 has been a family car since it was new. So if im going to build one that will be it. Plus i already have the heated seats and a ipd keyless entry kit in the trunk. I will start looking for a B230ft then and start from there. Can you increase the fuel output to allow for higher boost with that system or do you have to install a 5th injector or both.

 

I wonder what the stroker crankshaft came out of.

 

you'll want to use the fuel pump from the 940 turbo, it delivers way more fuel (and your gas mileage will prove it!). the LH2.4 injection/ignition on the B230FT is fairly different than the old CIS system you have. its electronic injection, all 4 injectors spray at the same time, twice per turn of the crank (so 4 shots per ignition cycle in each cylinder). LH2.4 uses a ECU and seperate ICU (ignition) which are both mounted in the passenger footwell, its distributor ignition and the primary timing source is a crankshaft position sensor mounted above the flywheel... It should be pretty straight forward to take the whole engine harness from the 940 and drop it into your car. I'd try and squeeze the 940's radiator and intercooler in, too

940 Turbos dropped the separate oil cooler stacked with the radiator, and instead they plumb coolant through the oil filter mount. they do pump ATF through the radiator for automatic transmission cooling. 92+ 940's got a larger radiator with larger electric fan and no mechanical fan

 

Pretty much i want to try and find a wrecked 940 manual turbo to do my swap. Im already set up with an electric fan. Gramps did that when he put the intercooler in. Can an external oil cooler be used instead? I dont like oil flowing next to coolant just a personal thing i guess.
